With the increase in interest in web based e-commerce, the amount of business that is transacted on-line and the explosion in the amount of services available, the ability to

  <description><![CDATA[The past few years have seen significant work in mobile data management, typically based on the client/proxy/server model. Mobile/wireless devices are treated as clients that are data consumers only, while data sources are on servers that typically reside on the wired network. With the advent of pervasive computing environments, an alternative scenario arises where mobile devices gather and exchange data from not just wired sources, but also from their ethereal environment and one another.

  <description><![CDATA[Security is a critical problem in dynamic and open distributed
environments such as those enabled by the semantic web and pervasive computing technologies. The presence of heterogeneous entities that
are neither pre-determined nor permanent, and the lack of central
control are some of its challenges.  We believe that declarative
policies address this problem while maintaining openness and
flexibility.  We propose the use of policies defined in OWL to

However, whether for selfish or malicious reasons, a node may fail to cooperate during the network operations or even attempt to disturb them, both of which have been recognized as misbehaviors.

  <description><![CDATA[We propose a proxy based solution to secure web access from un-trusted machines. 
Traditional proxy based solutions require constant out of band communication with the proxy. 
However, our system does not require constant communication with the user. Instead, the user 
carries a mobile device capable of performing cryptographic operations to generate onetime 
passwords. These passwords are then used to authenticate to the proxy. We have developed a 
prototype system and tested its perfor...]]></description>

  <description><![CDATA[There have been two parallel themes in access control research in
recent years.  On the one hand there are efforts to develop new access
control models to meet the policy needs of real world application
domains. In parallel, and almost separately, researchers have
developed policy languages for access control.  This paper is
motivated by the consideration that these two parallel efforts need to
develop synergy.  A policy language in the abstract without ties to a
model gives the design...]]></description>

Online social networking systems are a phenomenon that has grown exponentially over the past few years. These systems provide platforms for people to easily share information, especially about themselves and about their interests.  With the recent emergence of geolocation technologies, social networking can allow users to interact relative to location and time. Most systems began with few or no privacy controls and have gradually been adding and enhancing them to meet the ...]]></description>

Role Based Access Control (RBAC) is a flexible and powerful approach to access control which is widely used. We present approaches to finding the functional role hierarchy using access logs. We discuss a method to reconstruct the functional role hierarchy with knowledge of all access rights of all users. New methods of test data generation are introduced.  We then present heuristics that work with partial logs to predict an approximate role hierarchy. A method to effi...]]></description>

  <description><![CDATA[A mobile ad-hoc network (MANET) is a collection of wireless, self-organizing nodes, each capable of routing network traffic and having the ability to be mobile.  A MANET has no central authority nor fixed network infrastructure, and the dynamic nature and openness of MANETs lead to potential vulnerabilities.  Since there is no guarantee of connection to the wired Internet, accepted security practices involving third party authentication servers becomes an unrealistic expectation.  Even with a...]]></description>
